DESCRIPTION
The 603-1 and 603-2 optically coupled solid-state
relays are rated at 2 Adc and 5 Adc at 50 Vdc,
and are available with TTL compatible inputs.
Packages are available in three different
configurations with a choice of screw terminals,
quick disconnect terminals or through hole solder
pins. This allows for maximum flexibility for
mounting onto printed circuit boards, panels, or
heat sink mounting with optimal mechanical and
thermal considerations.
The 603-3 and 603-4 relays were designed
specifically for high-voltage loads up to 5A at 250
Vdc. They utilize a Teledyne transformer coupled
driver/isolator to provide high input/output isolation
and low offstate leakage. The adaptive package
design offers a choice of screw or quick
disconnect terminals for chassis, panel, or heat
sink mounting, and solder pins for direct mounting
on PC boards.
